CARL L. NELSON, OF SEATTLE, WASHINGTON, ASSIGNOR, BY MESNE ASSIGNMENTS, TO THE NATIONAL CASH REGISTER COMPANY, OF DAYTON, OHIO, A CORPORATION OF OHIO, (INCORPORATED IN 1906.)

CASH-REGISTER.

Application filed June 10,1905, Serial No. 264,610. Renewed May 10, 1915.

To all whom it may concern Be it known that I, CARI. L. NELSON, a citizen of the United States, and a resident of Seattle, in the county of King and State of \Vashington, have invented a new and Improved Caslrliegister, of which the following is a full, clear. and exact description.

My invention has for its principal objects the improvement and simplification of cash registers and provision th'ereof with means for accomplishing certain new results.

More specifically the objects of the invention include, among others which will appear below, the provision of an automatic drawer-operated machine with means for not only registering the amountof the purchase or transaction in such a manner as to show figures which can be read from both sides of the machine on account of transparent indicators, but also for presenting these figures in their normal position instead of that which is usually a feature of cash registers; also means for printing details or separate transactions, and totals in different colors (the means for printing totals bei g adapted to print any desired figures) means for printing slips or checks which can be taken from the machine; means for locking the keys and unlocking each one in a set when another in the same set is operated, thus permitting correction if the wrong key is struck and the error is discovered before .the amount is registered; providing an improved zero-setting device; mounting the machine so as to permit of turning it into any desired position, and providingother features for the general improvement of cash registers.

Reference is to be had to-the accompanying drawings forming a part of this specifi cation, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a perspective view of a cash register embodying my present improvements; Fig. 2 is a plan of the same with the covering frame removed; Fig. 3 is a rear elevation without the cover; Fig. 4 is an elevation of the right end ofthe machine without the cover; 5 is an elevation of the left end of the machine with the cover removed and parts shown in section; Fig. 6 is a sectional \iew on the line (36 of Fig. 8; Fig. 7 is a sectional view on the line 'l'7 Specification of Letters Patent.

Base of the machine-For the purpose of supporting the machine in such a way that it can be turned into any desired position, I provide a base 30, shown in Figs. 13 and 14. This base is provided with a depression 31, upon which is a circular body 32 having a series of inclined surfaces 33. Upon this circular body is mounted a plate 34. This plate is centered by a pin 35, preferably located in line with the center of the machine, and is provided with a handle 36 rigidly connected therewith and extending into a position from which it can be manipulated by the operator, and designed for turning the plate. The plate is provided with lugs 37 having inclined surfaces ada )ted to engage the inclined surfaces 33 an to ride up upon them when the handle is'turned. The plate 34 is provided with an annular groove 38 for receivin ball-bearings 39 or the like. On these ball-earings rests the underside of a table 40, which is also centered by the pin 35, and is adapted to rotate about the latter. The operation of this part of the device is very simple. \Vhen the handle 36 is in the position shown in Fig. 13, the inclined surfaces 37 are in the position shown in Fi 14, and the table rests upon the base 30. FVhen the handle, however, is oscillated against the right-hand edge of said depression, the. surfaces 37 are forced to move upwardly along the surfaces 33, and this raises the plate 3% so that the table supported by the bearings 39. In this position the table can obviously be rotated by hand in a very eas manner to any dosh-erv position.

chic and frame.-'lhe table is provided with a cover 42 (Fig. l) which is removable from the table. and supports the various arts of the frame or casing. The on ing itself is shown as consisting or St 'ral. parts forming ends -13. a top ii. a. front-side -15. and a rear-side 46. One end 43 is provided with a removable panel 43 having a slot 43 for a purpose to be described. The top is provided with an extension 44. having transparent walls and top 47. The front may be made in several pieces and provided with a slot al for viewing a counter, and with a second slot 49 for a printing lever. In the front of the machine located a small casing 50. which can be readily re moved, and which is provided with openings 51 and 52 in its front and end walls respectively and lVithin the casing are a pair of longitudinal side-walls 03 having numerous passages and openings for receiving the various parts of the mechanism. and for supporting them. T have are several other details which constitute a part of the name, and which will be referred to in a description of the elements with which they are connected.

Drawer operating me /maism.-- lhe table is hollow (see Fig. 5) and is provided with a drawer 54 which preferably provided with compartments 55 and has a plate 56 at the rear. Above the drawer the table is provided with a plate 57 for supporting part of the operating mechanism for the drawer (Figs. 12 and 15). Upon this plate is mounted a lever 58, the latter being pivoted to the plate by means of a pin 59. This 1ever is connected, by means of a c ain 0 or other flexible connection passing around a pulley 61, with the drawer. This chain is shown as being connected with a hoek 62 mounted on a. bracket 63 mounted upon the plate 56. A spring 6% mounted on the plate 57 normally pulls the lever away from the ulley 61 and constantly exerts a motive orce for openingthe drawer. At the beinning of the motion of opening the drawer 'it is retarded by the bearing of a roller 65 on a short arm (16 of the lever 58 against a cam surface .57 on a bar (58. The purpose of this to avoid the rapid motion which. would be given to the drawer by the motor spring (H. and to permit the drawer to close with a snal motion at the end of the stroke. The bar 68 is connected (see Fig. 5) to a pair at slidesllf! movable on the plate'5'7, and it is normally forced toward the roller 65 by means of a motor spring 70, which although acting to produce motion in the. same direction as the spring 64 is designed especially for another oilice which will be described below. The motion of the bar 65 is kept in a straight line by means of the slides 65?, as they are constrained to move in parallel lines by the embpieces 53 of the frame against which they are placed, and by a projection 69 (Fig. 12% moving in a slot 57 The plate is provided with a rack 71 (Fig. 12) along which the bracket 63 passes. In order to prevent the drawer from being partly opened or closed and the motion stopped without completing it, this bracket is provided with a. hanging pawl 72 (Fig. 1a). This pawl is pivoted at a point well above its center of gravity, and on the lower part is provided with two notches 73 (Fig. 12.3) having oppositely extending teeth 74 below them. As the pawl passes over the rack in either direction it will be forced to the rear with respect to the direction of motion. and one of the teeth 74 passing along the top of the rack will be at all times in a position to engage the rack and stop the drawer it it is attempted to move it in the other direction. lVhen the end of the rack reached. however. the pawl is permitted to drop from it so as to assume the position shown in Fig. 15, and then upon reversing the motion of the drawer the same conditions are repeated. The plate 57 is provided with a slot 75 for receiving the pawl and the bracket (ill. The bracket 63 is provided (Figs. 15 and 26) with a projection 76 extending to th rear. and a projection 77 eX- tending to the side and by which it is guided below the cover-plate 57. It is also provided with a cam surface 78 which projects through the slot 75 and engages certain mechanism which will be described below. The plate 5 has a slot 57 through which the projection 77 can be inserted.

From the construction so far described, it will be seen that the opening of the drawer by the operation of the spring 64 causes the bar (38 to moveto the front in Fig. 12 a cerlain distance. taking, with it the slides 69; also that the bracket 63 is simultaneously caused to move with the drawer throughout the length of the slot 75. carrying with it the pawl 72. the latter passing over the rack 71 and preventing the movement of the drawer in the wrong direction. It will also be seen that the drawer is compelled to start to open with a slow motion. and that after the start is made the motion will increase, according to the natural acceleration of speed due to the s 'iring 64. while in closing. the drawer can be forced back against the resistance of the spring. and at the end of the stroke it can easily be moved to its extreme position.

[)rau'rr Zm-Zrz'ng] and rrlcaxz'ny; device. in closed position the drawer intended to be held by the operation of a pin 79 (Fig. 7)

passing through a slot 80 in the table, and normally dropping by gravity in front of a projection 81 on the drawer. This projec tion has a slanting surface 82 at the rear in order to assist in forcing the pin up when the drawer is closed. and assure that it will reach the top of the incline and fall behind the projection. This pin therefore automatically locks the drawer in closed position when it is forced to the end of tits stroke, and it must be displaced before the drawer can be opened. In order to accomplish this result the pin extends upwardly some distance from the top of the table. and is provided with a guide 83. It is also provided with a passage or notch 84 through which passes the end of a bar 85 (Figs. 7, 21 and 22 This bar is provided with a slanting or cam surface 86, which upon being moved to the rear will engage the top of the slot 84 and lift the pin. For the purpose of moving this bar it is pivotally connected by a bolt or pin 87 with a bell crank 88. which is pivoted upon a shaft 80 passing through the machine from one end frame 53 to the other. This bell-crank is shown (Fig as being duplicated at the two ends of the machine. the two parts of it being connected by an operating bar 90. This operating bar pref eranly extends across the front of the machine Su that it will be within eas reach of an operator at all times. Obviously the de pression of the operating bar causes the reciprocation of the bar 85 to the rear, and the engagement of the surface 80 with the pin 79 so as to raise the latter and allow the drawer to be opened by the mechanism described.

Keys and A-cy-lock/ng 1)1cc/mm's/n.- ()n the shaft 89 are also pivoted several sets of keybars 01 (Fig. 7). Each key-bar is normally held in elevated position against a rod 92 by means of a spring- 93 t-(mnccted with a bar 91 passing across th machine. Each key is also provided with a projection 05 extending below and having a tooth 00 upon one side thereof thereby providing two spaces 97. On one arm of each bell-crank S8 is slidingly mounted a cross-bar 08 which is adapted to enter the spaces 7 and lock the keys in their raised or depressed position. This bar is normally forced under tension by a spring 00 into said spaces. but under certain conditions it is held away from the pro-- jcction 05 by means of a bar 100 mounted upon each of the bell-cranks. This bar is held in a depression 101 in the l'iell-crank and is rigidly connected with the bar 08 so that it prevents th latter from yielding to the sprin 09 beyon a certain point. 'hcn the operating bar is u pressed. the short arm of the bell-crank moves to the rear of the shaft 89 and permits the bar 98 to move inwardly with it. but when the operating bar is raised, the rod 100 being forced to-the front by the short arm of the bell-crank holds the bar in a position toward the front where it will not engage in the spaces 97. This motion is permitted on account'of the fact that the bar 98 can slide in slots 102 on the two end frames When this bar is in the position shown in Fig.7, the keys can be depressed and raised at will, but when the operating bar is lowered the cross-bar will move into the spaces which are opposite it and lock all tlie keys, either in depressed or raised position, according to their condition. On reference to Fig. 2 it will be noticed that the keys are arranged in several sets, those shown being sets for registering different columns of figures, -with two additional sets, one for registering an initial, and the other for registering other matters, as for example, charged, received, and paid. The keys are designated according to the matter that they are intended to register. I have provided an error-correcting device for each set of keys. whereby if the wrong key is struck and the error is discovered before the manipulation of the operating bar 90, it can be corrected merely by striking the right key. For this purpose (Figs. 7 and 9) I have shown a. rod 103 on which are pivoted a series of plates 104, one plate for each set of keys. Each of these plates is provided with a projection 105, and each of the keys is provided with a projection 106 having a notch 107 adapted to engage the end of the projection 105. All the keys of one section are so arranged as to permit their notches engaging the projection 105, and it will be seen that when a key is depressed these parts register with each other and the key is held temporarily in depressed position. In depressing the keys sufficiently to cause them to be locked in this manner they have to be forced to a point farther down than that at which they remain after being locked. If the wrong key is depressed. the depression of another in the same set will force the plate down to this low point, and will release the key already locked. while retaining the key being depressed and locking that when pressure is removed from it. This provides for the correction mentioned above, and it also prevents the registering or attempted registering of two figures in the same set of keys.

In order to release the keys after the registering operation is entirely completed, the plates 104 project to the rear far enough to be engaged by pins 108 on a rotatable rod 109 which passes across the machine. A spring 110 normally holds each plate in elevated position, but the oscillation of the rod 100 will obviously depress all the plates and unlock all the keys that may be held by them. In order to accomplish this result automatically when the drawer is closed, I provide the rod 109 where it passes through the left-hand frame 53 with a swinging pawl 111, (Fig. 5,) having one surface curved and the other surface being provided with a tooth. Thispawl has an inclined rib 112, which upon moving to the rear engages a screw or stud 109 on the shaft, and carries the shaft around with it. On the slide 69 which is located on this side of the machine is placed a pin 113 which is adapted to engage the pawl 111, and upon its rearward motion will rotate the rod 109 sufficiently to cause all of the plates 104 to be depressed and release the keys and operating bar. The operating bar is provided with a tooth 114 (Fig. 21) which engages the right-hand plate 104: when the operating bar is depressed. This feature operates in the samemanner as the keys. \Vhen the operating bar is released by rocking shaft 109 it ascends and carries the cross-bar 98 into an outward or unlocking position. The keys will then fly up on account of the operation of the springs 93, if the bar 98 is out-of engagement with the spaces 97, which will be the case at this time because the operating bar has been raised as described. The keys are therefore in condition to be depressed.

Indicating dem'cc.--The projections 95 on the keys bear upon the plates 115 (Figs. 6 and 7). One of these plates is provided for each of the sections of keys, and they are preferably pivoted upon a rod 116 which is mounted upon a pair of standards 117 constituting a part of the frame. These plates are normally held in elevated position by springs 118 bearing upon the shaft 103 or upon any other convenient part of the machine. Located upon a plate 119 above the table are a series of slides 120 normally urged toward the front of the machine by springs 121, (Fig. 6). The machine is provided with one of these slides for each section of keys, and each slide carries a standard 122 bearing a plate 123 having a series of teeth 124 upon its front edge as shown in Fig. 17. The number of teeth is equal to the number of figures or other characters to be registered in the set to which the plate belongs. .The front tooth represents the first character, as for example zero in a set of numbers, the second 1, and so on to 9. When the plate 115 is in elevated position the first step or tooth is against it and the machine is in condition to register zero. When one of the keys is depressed, the end of the plate 115 is removed from the teeth, and the projection 95 upon the key depressed is placed in the path of the plate 123. The keys are so arranged that thes e depressions are in front of these teeth in regular order. For instance, key No. 1 is directly in front of the tooth which corresponds to the numeral 1 and which represents a single step from the zero key. Consequently when a key is depressed and the slide is permitted to move forward by means to be described, it will move up to such position that the proper tooth will engage the projection on the key which is depressed, and this constitutes a limit for its motion. But when 110 key of any particular set'of keys is depressed, the manipulation of the operating bar will not allow the parts connected with that set to move at all, because the first tooth of the plate 23 of that set is in engagement with the rear of the plate 115.

Each slide 120 is provided (Figs. 6 and 9) with a downwardlyextending projection 125 which passes through the plate 119 behind the bar 68. The latter is intended to keep all of the slides 120 in their normal position when the drawer is closed, but When open this bar yields and consequently all the projections 12. are allowed to yield, and forced to do so by the springs 121, a spring 121 being employed to operate the slide which is at the right. Upon moving in this way when the drawer opens, these slides will be stopped at a distance of one or more steps from their original position, according to that key which is depressed. Located adjacent to each slide is an indicator carriage 126 (Figs. 3 and 6), preferably running on wheels 127 in a direction parallel to that of the motion of the slides. Ilach carriage is provided with a bottom plate 128 which slides upon the top of the plate 119. The rear surfaces of these plates are located in the path of the projections 125 corresponding with the same set of keys, consequently as these projections are drawn forward with their slides by means of the springs 121 and 121, they will engage the carriages and move them a distance equal to that which they move themselves. The carriages are impelled toward the rear by springs 128. Each of these carriages supports a pair of guides 129, each guide being provided with a series of slots 130 equal in number to the number of keys in the set cor responding to that particular carriage. In these slots are guided a corresponding series of indicator-holders 131. Each of these holders is provided preferably at the top with a casing 132, in which is mounted an indicator 133. These indicators are preferably formed of glass or other transparent material. and the numbers which indicate the transaction to be registered are preferably placed upon the front side. and instead of each number representing the whole number corresponding to that on the key, they are designated in. such a manner that the number shown at the front appears in the regular order. In many cash registers as. heretofore constructed the indicator corresponding to a number of two figures, as for eXample 20 oents,, hears.the numeral 20?,

and accordingly, when another numeral is rung up. the number appearing on the register does not clearly indicate the amount registered, because in the case of 21 cents the numbers appearing insight are 20 and 1. In the present case, with the same number, the ordinary figures would appear for the indicator representing 20 cents is supplied merely with the numeral 2. The same principle is carried out throughout the machine.

It will be readily understood that with the mechanism so far described, the position of the indicators is controlled by the keys,'and that there must be a line across the machine which will intersect all of the indicator supports which correspond to the keys depressed, or to the Zero keys befonging to those sets in which no number is to be registered. This line is the line directly under the indicator supports of the zero indicators when-the latter are in the normal position, and all that it is necessary to do in order to move the proper indicators into a more elevated position, where they can be seen from the front and back, is to place a bar 134 across the machine in a position directly under the original position of the zero indicators, and, to raise this bar in such a manner as to elevate all the indicator-holders which are above it and rest upon it. This bar 134 is mounted upon sliding bars 135 (Figs. 7 and 9) guided to move vertically by guides 136 and by segments 137 meshing with racks 138 on the sliding bars and mounted on a shaft 139. In order to manipulate these parts one of the bars 135 is provided with a projection 140 to which is pivoted a connecting rod 141. This connecting rod is provided with a stud 142 (Fig. 4). This stud projects through a curved slot 143 op the right-hand side plate 53, and its upper surface is inclined so as to form a good seat for a catch 144 which is mounted upon a lever 145. -This lever is pivotally mounted upon a lever 146 pivoted at 157 ,and is normally held in such a position as to readily engage the stud 142 by a spring 147 The lever 146 is provided with a stud 148, which if desired may extend through a slot 149 in the side plate so as to receive an operating spring 150 which normally holds the lever 146 in elevated position and returns it to that position when displaced. The bar 134 has a stud 151 (Fig. 5) passing through a slot 152 in the left-hand side plate, and provided with an operating spring 153 for lifting the bar. These parts provide for: lifting the bar 134. exposing the indicators which correspond with the keys depressed, and leaving the parts in such position that the catch 144 is free to engage the stud 142. The lever 146 is provided with an inclinedand elonguted slot 154 (Fig. 4) through which passes a projection 155 upon one of the operating levers 88. This projection passes through a slot 156 in the side frame, and obviously when the operating bar 90 is depressed it ,will act upon the lever 146 through the slot 154 to turn it about its pivot 157, and this operation will cause the stud 142 and consequently the bar 134 to be depressed. Therefore, the depression of the operating bar results immediately in the lowering of the indicators which at that time appear in sight, or in other words, the indicators which represent the last sum registered. The withdrawal of the bar 134 below the bottom of the indicator-holders 131 permits them to move with the bars 120 to positions determined'by the plates 123, and as the drawer slides open a tripping finger 158 which is moved with the drawer engages the lower end of the lever .145 and disengages the catch from the stud 142. This permits the spring 153 to elevate the bar 134 and raise the indicators which correspond to the keys struck. When the operating bar is again raised the lever 146 will be raised with it, and the catch will engage with the stud as before, ready to repeat the operation.

The finger 158 is mountedupon a plate 159 which is normally forced toward the front of the machine by a spring 160 shown in Figs. 4 and 10. 'This plate is provided with a spring or detent 161. having a head 162 thereon, provided with slantingsurfaces. A spring 163 engages at the rear of one of these surfaces and normally holds the plate in its position at the rean of the machine, but the drawer opens, the cam surface 78 (Fig. 15) engages the lower side of the head 162, forces it out of reach of the spring 163 and permits the spring 160 to pull the whole plate to the front, when the drawer has reached nearly its outmost position exposing the indicators. This causes the finger 158 to engage with the lever 145. The lever 145 is provided with a spring 164 against which the finger 158 is stopped as long as the lever is in depressed position.

Printing nwchaniem.-Each of the differentially movable indicator controlling bars 120 is connected with a cross-bar 165 (Fig. 3) which passes through a perforation 166 in one of the side frames 53. These crossbars are nested and are connected in any desired way with longitudinally slidingbars and 1Q. These may be given any convenient location with respect to each other, but

I have shown the former as being mounted at the top of a column 172 and the latter as being mounted at the front end of the bar 167. Both of these printing surfaces are provided with type corresponding to the keys with which the bar is connected, and these type are arranged in regular order as will be readily understood. The type surface 171 is designed for printing slips or checks inside of the machine. For this purpose the machine is provided with guides 173 (Fig. 1) having a passage between them for the reception of the checks. The checks are slipped into the passage above an, inking ribbon 171 (Fig. 4). This inking ribbon is mounted upon rollers 175 and 176, which are provided with thumb-wheels 177 for operatmg them in order to adjust the inking ribbon as desired to provide a fresh surface. Above the inking ribbon is a hammer 178 pivotally mounted on a shaft 179 and normally pressed downwardly by a spring 180. This hammer is provided with 3. lug 181 adapted to be engaged by a cam 182 (Figs. 4, 10 and 23) on a lever 183 which is pivotally mounted upon the sliding plate 159. When the head 162 is released in the manner described above, the sliding plate 159 moves to the front and the cam 18; causes the pin 181 to ride up its upper inclined surface and to drop off the upper edge thereof, the spring 180 forcing the hammer down, when permitted by this cam. onto the back of the inking ribbon. 'A blow is thus delivered which will impress the type upon the check or slip. This mechanism has several minor features, comprising an adjusting screw 18% and a spring 185 to hold the hammer up slightly from the paper, these being mounted upon a plate 186 which guides the inking ribbon. pin 187 above the roller 176 also assists in guiding the ribbon with respect ('0 the lilSt-IlltlltlOfltKl plate. The lever 183 is provided with a tongue i548 and with a socket 189 in which works a lever 190. (Figs. 1.. ll and This lever 190 is piw oted to the frame by a stud 191, and being operated upon each motion of the sliding plate 159 or of the lever 193 its upper curved portion 19; engages at each stroke of the drawer with a le er 19 (Fig. which passes through a slot in the side plate 53, and by pawls 194 and 191 opcrutrs by a step-lrv-stcp motion a gcarwvheel 195 against the forceof a spring 19 3. This provides for feeding intermittently a roller 197 which carries an inking ribbon We. preferably made to print in two colors on the sides of the center thereof. (Figs. L and i.) This inking ribbon passes through the side plate 53 to a point above the printing surfaces 170. l have indicated this ribbon as being provided with blue ink upon the rear half and red ink upon the front, the blue-ink half being designed to printfroin this printing surface, and being located in such position that the type will be moved under it when the bars 167 are moved by the mechanism described above. A pivoted frame 197 carries a. roller 198 which presses by gravity on the ribbon to keep it taut.

For causing the impression to be made the following mechanism is provided: The slides 69 are each provided with a rack 199 (Figs. 4 and 5). These racks mesh with pinions 200 upon a shaft 201 passing through the machine, and obviously when the drawer is opened or closed the pinions and shaft will be rotated through a portion of a revolution. One of the pinions is provided with a pin 202 adapted to engage a lever 203 pivotedv to a side plate 53 and connected with a bar 204. This bar reciprocates in a guide 205, and at its upper end is provided with a projection 206 for engaging an arm 207 which carries a printing hammer 208 (Fig. 11). This arm is pivotedv upon a stud 209, and has a projection 210 with which springs 211 engage for the purpose of normally holding it in a certain position and forcing it into a printing position when the necessary mechanism is operated. On the rod l-ll is a stud 212 projecting through a slot 213 in the side frame .33, and engaging a ram surface 214 on a lever 215 which is pivoted on a shaft 219. This lever is normally held in a certain position by a spring 217, and is pro vided with a cam surface 218 having an undercut rear end. The arm 207 is pro vided with a projection 219 which normally rests upon the top of this cam 218, and

occupies the position shown in Fig. 4. The operation of these parts is very simple: lVhcn the shaft 201 is caused to rotate'by the operating movement of the drawer in the manner described, the pin Q02 releases the lever ".203. allowing arm QUl and projection 206 to dri p. its the bar 13% is at this time in depresscail position and cam 21S moved rearward. the projection 219 drops slightly until it rests on cam 218. and conseqiuiently when the. bar 1354 moves up as the projection 15S strikes 15, pin 212 will rise and allow 21% to move forward from under 219 when thelninnner drops to make an impression. the projection ".519 slides over the rear edge of this cam and rests upon the top surface of it. As the bar 13H is raised. the stud 212 slides down the inclined surface of the arm ill and permits the cam 218 to be withdrawn from its position by the spring 217. By this time the pin 20; has permitted the lever 1503 to drop so that the projection 206 does not interfere with the operation of the arm .507, and the latter is forced into a striking position upon the back of the blue portion of the inking ribbon. and provides the impression. The rear of the lever .203

acts as an abutment for the cushioningspriug 161.

As shown in Fig. 18, the paper 220 upon which the impression is to be made is provided with a loop 221 in its end, which is passed over a pin 222 fixed to a roller 223. This roller is mounted on a shaft 224, and after the paper is put in place it is secured in position by a slotted sleeve 225 which is passed over the roller. The paper is then Wound up on this sleeve, and this operation is made automatic by the provision of a ratchet-wheel 226 on the roller, and a pawl 227 movably mounted upon the slide 201. This pawl is preferably pivoted and is provided with a spring 228 to force it into 'engagement with the teeth of the ratchet wheel. A spring 229 is employed to prevent the ratchet Wheel from moving in the wrong direction. The other end of the paper is wound upon a roller 230 rotatably mounted upon the shaft 231. The.paper passes from one roller to the other over a. plate or table 232 mounted upon one of the side frames '53, this table being provided with a slot 233 through which the type surfaces 170 can project, or below which they can be placed so as to permit printing by striking the paper above these surfaces with the hammer 208.

Total printing de'vice.The mechanism described above is provided for printing the details or separate transactions to be recorded. It is also desirable to provide means for printing totals or any other figures which it may be desired to place upon the paper or ribbon 220. In order to avoid confusion the ribbon 198, as has been stated, is provided with a red and a blue portion, the blue being shown as so located as to receive an impression from the hammer 208; the red is designed for printing totals. livotally mounted upon a shaft 234 is a lever 235 (Fig. 7). This lever projects through the slot 49 of the casing and has a handle by which it can be readily operated. It also extends through a slot 236 in one of the side pieces 53, and engages a sliding plate 237 located above the table 229 (Fig. .11). This plate is provided with a pivotal pawl 238 having a projection 239 (Fig. 24) affording two cam surfaces. Immediately under this pawl is a spring 2 10, the rear end of which is rigidly mounted upon the slide 237. Iivotally mounted upon the shaft 231 is an arm 241 upon which is mounted a hammer 242. A spring 243 forces the hammer to its lowermost position. The movement of the slide 237 causes a projection 241 on the hammer to ride up the upper inclined surface of the projection 23 and to drop from the upper edge thereof as the pawl passes by. It strikes the red part of the ribbon above the paper, and any type which may be beneath will consequently make an impression. As the projection 214 drops, it lands upon the spring 240, and the forkeys that represents numerals.

ward motion of the slide brings it under the nose of't".e pawl and beyond it, so that it is ready to Slide up the inclined face upon the repetition oi the movement described. As the principal object of providing this mechanism is to afford means for printing totals, it is desirable tha means also be provided for feeding the paper 220 a greater dis tance when this mechanism is operated than that which it is fed ordinarily when the details are printed. Accordingly, the slide 237 is provided with a pivoted arm 245, having a tooth 240 for engaging the ratchet wheel 220. The movement of the slide is sufiicient to cause the tooth 246 to move to the rear a distance of two or more teeth on the ratchet-wheel so as to give a greater feed to the paper or ribbon than is accom plished by the pawl 227. The lever 235 has a projection 217 (Fig. 7) adapted to engage the arm 2-18 of a registering or counting device 210, to register the total numberof operations.

Adding mcchanism.1n order to provide for presenting the proper types to a printin g position and to provide for automatically adding the numbers as they are registered, I have shown the following mechanism (Figs. 6 and 7): Each slide 120 is provided with an upwardly extending portion 250, having a horizontal rack 251 at the upper end there of (Fig. 9). This rack meshes with a' segmental gear 252. It will be understood that there is one of these gears for each set of Those representing other matters need not be provided with adding mechanism. On a shaft 253 are a series of concentric tubes 254 (Figs. 8 and 9), and each of these tubes is adapted to be moved by the segmental gears. These tubes extend through one of the side plates 53, and each one is provided with a type-wheel 255. These type-wheels are provided with type corresponding to the characters or numbers to be registered, and it will be obvious that when the slides 120 are moved to the front and stopped by the plates 123 engaging the projections 95 of the key levers, the segmental gears will be rotated a distance repm-sented by the particular teeth of the plates 123 that engage the projections of the key-levers. This operation obviously rotates the type-wheels. and the type are so placed upon them that the distance traversed by the racks 251 is accurately represented by the type number brought to the top of the several type-wheels. If the registration is started from zero, the numbers brought to the top of the type\vheels upon the first op:

"l 'd are provided with projections of the ribbon. The operation of the machine without manipulating any part independently, causes the number to be printed from the blue ribbon by means of the hammer 208, and if it is desired to print the number from the red ribbon it can be done by manipulating the lever 235. The typewheels do not oscillate in the manner correspondin to the reciprocation of the type surfaces 1 0, but at the end of each operation they remain stationary and at the next operation are carried on from their former position; therefore they accumulatively record the several numbers registered, and at any time they are in a position to print the sums of all the numbers which have been registered since the operation 'of the machine was commenced. and all that is necessary in order to print the total is to ring up no sale and manipulate the lever 235.

Each of the segmental gears 252 is pro vided with a pawl 256 forced by a spring 257 into engagement with the teeth of a ratchet-wheel 258. A toothed pawl :25!) on a shaft 260 is pressed by a spring 261 into engagement with-the same teeth and prevents backward motion of the ratchet-wheel. This construction provides for feeding the ratchet-wheel a number of teeth equal to the number of teeth of the rack 351 which are fed forward by the opening of the drawer, or in other words. the rotation of the ratchet-wheel is proportional to the motion of the rack 251 and is controlled by the key struck. wardly the pawl 256 slides along the teeth in an obvious manner, and the pawl 259 holds the ratchet-wheel in a stationary po sition at the same time, the adding taking place as the rack is returned to normal rearward position.

Thro'wout (la/vice for (II/(lino mcc/mnimrt. If it is desired to record a number without adding to the amount previously registered, this can be done by disengaging the pawl 256 from the ratchet teeth, and I accomplish this result by mounting a series of rods 262 on the shaft 234. These rods engage at the rear of pins 2625 upon the pawls 256, and when the shit it is oscillated to the front they operate toforce the pawls out of engagement with the teeth of the wheel and permit the gear segment to oscillate back and forth without rotating the ratchet-wheel, and consequently without advancing the type-wheels and adding the number registered to the total. This is especially dc- Sirable in recording amounts charged and paid, and the two keys marked (h an4d 2o (Fig. 7) which by means of links 265 are connected with arms 266 secured to the shaft Consequently the depression of these keys will operate the rods 2'32, and although the number struck on the keys will he print- \Vhen the rack is moved fored by means of the type surfaces 170 and 171. yet they will not be added to the total. urrying device.'ln order to provide for carrying 1 from a column to the next or higher column, and for accurately registering the same, I provide means for turning each ratchet-wheel 258 one step when the one in the column below has rotated ten steps from the zero point. ()n the shaft 201 is mounted a tube or sleeve 267 (Figs. 6, S and 9). This tube is provided with a cam 268, preferably having two teeth 269 oppositely disposed. The gear-wheel 200 upon one side of themachine is provided with a catch 270 (Fig. 19) normally pressed by a spring 271 toward the center of the shaft. Asv the wheel 200 is oscillated by the rack 19$) :1 distance sufiicient to turn it through more than half a revolution each time the drawer is opened. the catch 270 will ride up the cam surface 268 and engage one of the teeth 2639 upon one stroke of the rack, while upon the return stroke it will cause the cam and consequently the sleeve 267 to rotate through a half of a revolution. Upon this sleeve is mounted a drum 272, and this drum is provided with several series of teeth 273. Each series comprises in the/ present case two teeth upon opposite sides of the drum, and located at an angle with respect to each other in the several sets. There are as many sets as there are ratchet-wheels, lacking one. Located in the path of each of the series of teeth is a roller 27% mounted at the bot tom of a slide 275. This slide moves vertically in guides 276 and is provided with a pivoted pawl 27? and a spring 278 for forcin; the pawl into such position as to engage the teeth of the ratchetwhecl 258. It will be observed that upon each reciprocation of the rack 199. one of the teeth 273 in each set is caused to move past the roller 2H and raised the slide it it is not already in raised position. This causes the pawl 277 to rotate the ratclu't-whecl 238 one step. In order to cause this movement to take place only when it is desired to carry 1" from one column to another, a pawl 279 is loosely mounted upon a shaft 280 opposite each slide except that representing the units column. A spring 281 normally forces this pawl toward the slide, and the slide is pro vided with two notches or teeth 282 in which the pawl is adapted to engage. \Vhen the slide is down the pawl engages in the upper tooth, and when it is raised it engages in the lower one and consequently holds the slide in elevated position.

The pawl 27!) is wide enough not only to engage the teeth 282 but also to pass beyond the teeth of the ratchet-wheel 2.38 and into the path of a series of plates 283 upon a. disk 28% (Fig. 28). One of these disks is provided for each of the ratchet wheels except that representing the column of highest or-
